Philips DVD Player Error

I have a Philips DVD Player, model DVP3140/37. It suddenly stopped working.. it displays "err0r" when loading a DVD. I opened it up and sprayed some Dust Off on the lens, which looks clean, along with everything else, and still no luck. I tried using one of those CD/DVD cleaners (with the brush on the bottom), but that won't load either. Anyways, after looking over the inside, all the connections are good, but there was one piece that looked suspicious. It's a black part labeled C9 on the circuit board that has white goop around it.. this is something that I've never seen before. The goop is solid. It doesn't come apart when you poke it, but it's been sitting around for a while so it could have dried if it's discharge. Below are a couple pictures. Could this be the problem?
